Drum-level gage glasses have been reliably protecting deck-plates personnel and the public at large against boiler failures since well before the industry's oldest operator was born. But while today's direct- and indirect-reading drum-level instruments may look like those installed on your ageing heat-recovery steam generator (HRSG), improvements have been ongoing.

Cascade, Feed Forward and Three-Element Control controlguru. By Allen D. Houtz 1. One common application of cascade control combined with feed forward control is in level control systems for boiler steam drums. The control strategies now used in modern industrial boiler systems had their beginnings on shipboard steam propulsion boilers.
